Description

  • The MOD 1 features the same characteristics as our 308, with the addition of making more top end power. Upgrading the valve springs, a billet connecting rod, and billet flywheel are mandatory. A carb with a 1.33" or 34mm or larger venture is highly recommended. The use of big valves is also highly recommended.
  • The lobes are welded to increase durability, extending the life of this cam.
